T.C.F. Revue MensuelleAugust 1893 - De la Position du Cycliste

This is the earliest article that I have that was authored by Paul de Vivie. Aside from its author, it has nothing to do with derailleurs - it considers how you should set up your position on a bicycle. Perhaps it’s not pure science, but it is straight-forward, thoughtful, practical, sceptical and logical.
